Residential RIPE
Summary
Tarr Kft.
isp residential legacy
Tarr Kft. (TARR1) is a Hungarian regional internet, cable-TV and telephony provider headquartered in Szekszárd, in Tolna county, serving towns across southern and western Hungary.
What it's used for
- Residential broadband over cable and fibre, plus cable television and voice service to homes in the company's franchise areas.
- Business connectivity for local companies and public institutions in the same regions.
Notable
- An eyeball network: the rDNS is full of subscriber pools such as
pool128-5.cable.tolna.netandhNNN-NN.poolNN-NNN.dyn.tolna.net, which are home connections rather than servers. - Roughly 100,000 IPv4 addresses spread over a couple of dozen prefixes, typical of a mid-sized regional access provider rather than a national incumbent.
Interesting
- The
tolna.netdomain in the reverse names is a leftover from the company's origins as a county-level cable operator, and still marks most of its subscriber ranges today.

Classification and threat
Residential Fixed-line consumer ISP. Addresses here are homes.
Spamhaus DROP
Not on ASN-DROP The network as a whole is not listed.
No DROP prefixes None of its announced space is on the DROP prefix list.
Spamhaus DROP ("Don't Route Or Peer") lists space and networks run by, or hijacked for, spam and cybercrime operations: 442 networks and 1,773 prefixes, as published 2026-10-13. A short, high-confidence list, so a match is worth taking seriously, and absence from it says little on its own.
FBI IC3
No IC3 indicators Nothing from the FBI IC3 feed.
IC3 threat data is alpha. Absence of an indicator is not evidence of good behaviour, only of absence from this one feed.
